Patented Jan'.-13, 19'2o.

Application filed May 16, 1919. Serial No. 297,585.

To all whom it may concern:

Be it known that, I, JOHN B. HANo a citizen of the United States, residing at the city of Jamestown, in the county of Chautauqua and State of New York. have invented certain new and useful Improvements in Shuttles, of which the following,

taken in connection with the-accompanying drawings, is a specification.

The invention relates to shuttles for looms; and the improvement consists in providing a weavers shuttle with a steel casing for the butt of the spindle, and; spindle block by means of which said spindle'butt may be accurately and firmly locked in said spindle block while easily removable therefrom, the

steel casing and manner of-1ockingprovid mg crosswise'plns WhlCll are'held 1n said casing in such a manner as not to work loose or permit the spindle butt to work loose through constant shocks and strains in the "weaving processes on the loom thereby greatly prolonging-the life and efiiciencyof the shuttle; and the "invention consists in the novel features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is a top plan view of the improved shuttle with the central portionbroken away. Fig. 2 is a lengthwise vertical sectional 'viewof the butt end of the shuttle as shown at line 22 in Fig. 1. Fig. 3 is a perspectiveview of the butt end of the wood portion of the shuttle, the spindle and spindle" butt hold ing parts being removed. Fig. 4 is atop plan view ofthe spindle butt attaching end 1 of the shuttle with the spindle and spindle butt holding block removed therefrom. Fig. 5 is a crosswise sectional view at line 5-5 in Fig. 1 showing the construction and arrangement of the parts with the spindle removed. Fig. 6 is a perspective view, and

Fig. 7 is a side elevation of the spindle butt holding block. Fig. 8 is a perspective view of the improved form of hinging pin for said locking block. Fig. 9 is a'lengthwise vertical sectional view of the spindlebutt attaching end of the shuttle with a portion of the shuttle and spindle broken away. the

spindle being shown in the raised position.

Fig. 10 is a perspective view of one side;

and Fig. 11 a perspective view of the opposite side of the steel flanged holding casing for the spindle butt block for locking the same and holding the pivot pin for said block and. locking mett e" o th pindle casing or housing 26.

butt; and Fig. 12 is a perspective'view of Y the crosswise locking bar for the spindle butt removed from said spindle butt casing. gs. 13 and 14 show different elevations of the spindle butt, showingthe locking notches therein and the flattened side of the same to provide for its insertion in the spindle butt locking block; and Fig. '15' is an end elevation of the butt end of the spindle.

Like characters of reference refer to corresponding partsin the sevemrviews.

The numeral 20 designates the "shuttle shell or body which has'the central 'grooved and slotted portion in "the usual 'form excepting that at'theattaching end'for -the spindle 21, the opening is somewhat *en-- larged'and has the shoulders 22 and.'23 on its opposite "sides with the vertical grooves 24 at the ends of saidshoulders. "a crosswise groove 25 being provided at' thebottom'Inid- 1 way of thelengthoftlie shoulder portions 22 and 2B to'receive the struc'k u jshee't steel The casing or housing'26jisniade'U sliaped in front end, elevation, as shown inFigs; 5

The pivot pin 32 is preferably'made removable from the casing 26. The squared openmg; 35 at each side holdeachsquare ehd3 of the pin firmly in "position'whensaidpasing 26 is in normal position'inthechanneled opening 31 the squared ends 32 jofthe'pin 84: being held by the shoulders: thereon and the walls of the channeled opening 31. I I

The spindle butt socket block 33 the lengthwise opening 36 therethroughiwhich fits over the spindle butt 29. The socket block 33 has also the crosswise hole 87 for the pivot pin 32 and the cut'aw'ay under portiont felnd neon ta onnage, The

cut-away under portion 38 receives the looking cross bar 27 therein which bar 27 projects up into the path of the spindle butt 29. The crosswise pivot pin 32 also projects into the path of said spindle butt 29. The spindle butt 29 has the flattened portion 40 which accommodates the pin 32 and bar 27 so that said spindle butt 29 may be quickly and easily admitted to the lengthwise hole or socket 36 and given a quarter turn, thereby turning the notches 28 and 41 into locking conjunction, the notch 28 with the bar 27 and the notch 41 with the pivot pin 32, thereby firmly holding the spindle 21 by removably locking its butt 29 in the block 33, it only being necessary to give the spindle butt 29 of the spindle 21 a quarter turn back to permit its quick removal from the socket block 33.

The casing or housing 26 has the side,

flanges 42 bearing on the shoulders 22 and.

23 prevent downward movement of the casmg 26, and the end flanges 43 and crosswise flange 44 prevent endwise movement of said housing, thereby holding said casing or housing firmly in position in the wooden shell 20 and so braced as to take the constant strains and shocks incident to the process of weaving without working loose or permitting the spindle butt to work loose or any ofv its parts, all of the interlocking parts for the spindle butt being of hardened steel and having hearings in steel supports which'do not permit wear or change of form and give an added length of life to the shuttle.

It is obvious that the spindle butt and other parts of the shuttle are not changed to any great extent from the old wood form of shuttle so that the present designs of shuttles now in use may be quickly and easily adapted to my improvement by providing the channel shaped opening 31 with the shoulders 22 and 23 and grooves 24 and 25 so that the housing 26 with its crosswise locking bar 27 and squared end pivot pin 32 may be inserted in said shuttle, the spindle butt 29 being substantially the same as those now 111 use.

The spindle butt socket block 33 is preferably held in position by means of the screw bolt 45 and clamping spring 46, one end of whlch presses on to and works back and forth over the angular top 39 of said socket block 33.

The shuttle is used the same as any shuttle, the spool being inserted on the spindle 21 in the raised position, as shown in Fig. 9, after which it may be snapped back into place, the steel bottom portion 47 of the casing or housing 26 taking the shock of the downward snap of the spindle 21 as the socket block 33 snaps back into position within the casing 26. The squared ends 34 of the pivot pin 32 are firmly held in the squared openings or notches 35 so that said pivot pin has no opportunity to work loose, thereby preventing the spindle 21 and the spool thereon wabbling in its position within the shuttle shell 20.

I claim as new 1. A spindle shuttle comprising a wooden shell having a lengthwise opening therein for the spindle, a metallic housing removably attached in one end of said lengthwise opening in said shell and having squared openings in the opposite sides thereof, a spindle butt socket fitting within said metallic housing, and a pivot pin for said spindle butt socket having squared ends receivable in said squared openings in the opposite sides of said removable housing to hold said spindle in line.

2.

3. A loom shuttle comprising a Wooden shell having a-lengthwise opening therein for the spindle, a spindle butt having spaced notches therein, a metallic spindle butt socket block, a metallic housing for said spindle butt socket block supported in one end of the opening in said shell and having squared openings therein, a pivot pin for said socket block having squared ends receivable in said squared openings in said housing, a metallic crosswise projection in said housing for said pivot pin spaced to turn into looking conjunction with said notches of said spindle butt.

4. A loom shuttle comprising a wooden shell having a lengthwise opening therein for the spindle, one end of said openingspindle butt socket block fitting in said housing, a crosswise pivot pin for said socket block having squared ends receivable in said squared openings a crosswise metallic proj ection across the bottom of said housing, a spindle butt having spaced notches therein and a flattened side, said crosswise pivot pin and crosswise projection in said housing extending into the path of said spindle butt to be received into locking conjunction therewith by a quarter turn of the same.

5. A loom shuttle comprising a wooden shell having a lengthwise opening therein for the spindle, shoulders on the opposite sides of the walls of one end of said opening, said walls having vertical grooves therein at the ends of said shoulders, said wooden shell having a crosswise groove in the bottom of the said lengthwise opening between said walls, a metallic housing having flanges fitting on said shoulders and in said vertical and crosswise grooves to support and hold 1 i said housing against movement, a spindle butt socket block pivotally mounted in said metallic housing, said socket block having an opening in the lower side thereof, a crosswise locking bar in the bottom of said housing projecting into said opening insaid socket block, a spindle butt having spaced notches therein and a flattened side receivable in said socket block to lock the same in said block by turning into locking conjunction with said crosswise locking bar and a spaced projection in said socket block.
